<h4><a name = "tag_000_005_824">&nbsp;</a>NAME</h4><blockquote>
getwd - get the current working directory pathname
</blockquote><h4><a name = "tag_000_005_825">&nbsp;</a>SYNOPSIS</h4><blockquote>
<pre><code>

#include &lt;<a href="unistd.h.html">unistd.h</a>&gt;

char *getwd(char *<i>path_name</i>);
</code>
</pre>
</blockquote><h4><a name = "tag_000_005_826">&nbsp;</a>DESCRIPTION</h4><blockquote>
The
<i>getwd()</i>
function determines an absolute pathname of the current working directory of
the calling process, and copies that pathname into the array pointed to by the
<i>path_name</i> argument.
<p>
If the length of the pathname of the current working directory
is greater than ({PATH_MAX} + 1) including the null byte,
<i>getwd()</i>
fails and returns a null pointer.
</blockquote><h4><a name = "tag_000_005_827">&nbsp;</a>RETURN VALUE</h4><blockquote>
Upon successful completion, a pointer to the string containing the absolute
pathname of the current working directory is returned.  Otherwise,
<i>getwd()</i>
returns a null pointer and the contents of the array pointed to by
<i>path_name</i> are undefined.
</blockquote><h4><a name = "tag_000_005_828">&nbsp;</a>ERRORS</h4><blockquote>
No errors are defined.
</blockquote><h4><a name = "tag_000_005_829">&nbsp;</a>EXAMPLES</h4><blockquote>
None.
</blockquote><h4><a name = "tag_000_005_830">&nbsp;</a>APPLICATION USAGE</h4><blockquote>
For portability to implementations conforming to earlier versions of this
specification,
<i><a href="getcwd.html">getcwd()</a></i>
is preferred over this function.
</blockquote><h4><a name = "tag_000_005_831">&nbsp;</a>FUTURE DIRECTIONS</h4><blockquote>
None.
</blockquote><h4><a name = "tag_000_005_832">&nbsp;</a>SEE ALSO</h4><blockquote>
<i><a href="getcwd.html">getcwd()</a></i>,
<i><a href="unistd.h.html">&lt;unistd.h&gt;</a></i>.
